Laim Patent N 96,501, dated Nwemter 2,1869.

RAILROAD-CAR. VENTILATOR.

The Schedule referred to in these Lettera Patent and making part of the same We, OVERTON J. STYNER and JOHN EGAN, both of Lafayette. in the county of Tippecanoe, and State of Indiana, have invented a certain Device for the Ventilation of Railroad-0ars, of which the following is'a specification.

The first part of dur-invention relates to the application of :user-ies of movable automatic deiiectors to l the sides ot the car, to cause an outward current of air through the windows.

The second part of our invention relates t i a peculiar form 0f hinge for application to said detlcctors, which allowsthe'deiiectors to be operated automatically or otherwise, as desired.

Figure 1 is a perspective 4view of a portion of the side ofa railroad-cal', embodying our invention Figure 2 is a horizontal section through the windows and deiectors, the car supposed to be moving in the direction of the arrow.

AFigure 3 is a similar view, in which the car is supposed to be moving in a contrary direction.

Figure 4 shows the deflectors when so arranged as to be inoperative.

Figures 5 and 6 are enlarged plans of'thc lower hinge.

A is the side of a railroad-car, and

B, the windows. A

To the portions C of the side A, between the windows, are ailixed hinges, having screw-plates, D and E, for attachment respectively to the car and (lL/ticotor;and horizoirtal pintle-plates, l" G, forming with the pintle H, the hinge proper.

Attached to the plate F is a spring-catch, f, whose inturnedeml, f', is made to rest against a shoulder, g, ofthe plate G, or to enter a notch, y', ot' the saine.

The upper hinges have similar elements, 1) E F G, to the. lower hinges, but have no device for holding the detlvctors to any sta-ted position.

I 1 are deiiectors, which are attached to the plates E ofthe hinges.

The detlectors have a bevelled form, and their thick edge 'L is made to rest againstthe side ot' the car when the dccc-tor is in its operative position shown by -1, figs. l aml 2.

Then the motion of the car is reversed, the deector is carried around so'as to assume the position shown by l, in fig. 2,1 and I', in fig. 3; in this Aposition the shoulder' g of the plate Greets against the catch j" ofthe spring f, preventing further movement of the said deflector.

When it is desired to render the deiiectors unantomatic by the motion of the car through the air, theA catch f' is raised above the shoulder g,and the detlector swung around until its outside is parallel witl the side of the car, when the catch f' will fall into the notch g', and retain the deiiector in that posit-ion,

^ as seen in figs. 4 and 6.

The deflectors, it willI be seen, are in pairs, I I', each pair occupying the space C between two windows, and only one defiector of the pair is brought in contact with thc car at one time, the other being held out from the car, as seen in the drawings.

The act-ion ot' the deiectois is to cause'outward movements in the current ot' air passing along the side ofthe car, which establish outward currents through the windows, and prevent the entrance of dust.

l The outward direction given tothe air through the window does away with the nuisance of the 'wind from each window blowing almost exclusively upon the occupants ot seats to the rear of the window, and whereby each individual has the power of inconveniencing others without the ability to beneiithimself.

The airy for the `supply of the out-ward currents through the windows may be'allowed to enter the car through tine gauze, or be brought in contact with or through water to detain the dust suspended in it. A less complex form of lower hinge than that heretot'ore described has a shoulder or spur on .one plate,

F, which impinges against a similar stop or plate, G, and prevents the deilector swinging 4further outward than shown at l, tig. 2, and I', fig. 3.

In this form the shoulder upon' the plate F' performs t-he part oi' the lspriligcatch f f f shown in -the drawings, and the device is always automatic, there heilig no arrangement for holding the del'lectors in the position shown in iig. 4, where they are shown fixed with their outersides parallel with the side of the We claim, as our invention- 1. The deliectors I l. so arranged as tobe thrown in to and out of action by the movement of' the car,

orto be held in an inoperative position, substantially as described.

2.A In combination with the deilectors I I', the hinge D E Fff G, substantially as described.

1n testimony of which invention, we hereunto set our hands.
